Description

Technical Field

[0001] This utility model relates to the field of laser pointer installation technology, and in particular to a connection device that is easy to assemble and disassemble. Background Technology

[0002] In engineering construction fields such as mine development roadways and road construction tunnels, laser pointers are key measuring equipment. The ease of their installation and adjustment directly affects construction efficiency and project quality. In traditional technology, laser pointers are usually fixed using cement grouting bolts. This method requires drilling holes in the rock wall or roadway surface, injecting cement grout, and waiting for it to solidify before installing the equipment. This method has the following drawbacks:

[0003] Installation is complex and time-consuming: Cement grouting requires multiple steps such as drilling, grouting, curing and solidification, and the construction cycle of a single fixed point can be as long as several hours, which significantly increases the project time cost.

[0004] Poor adjustment flexibility: Once the pointing position of the laser pointer is fixed, if it needs to be fine-tuned or moved to a new position, the original cement base needs to be destroyed and reconstructed, which makes it difficult to repeatedly disassemble and reassemble the equipment and adapt to dynamic construction needs.

[0005] Therefore, this utility model proposes a connection device that is easy to assemble and disassemble in order to solve the problems existing in the prior art. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a connection device that is easy to assemble and disassemble. This connection device has a simple structure, is reliable in use, and is easy to assemble and disassemble, which can reduce the labor intensity of installing laser pointers, save time, and improve construction progress.

[0007] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a connecting device that is easy to assemble and disassemble, including a locking buckle and a fixing bracket. The locking buckle is used to lock the fixing bracket on the connecting base rod. The fixing bracket includes a first bracket and a second bracket. The second bracket is movably installed below the front side of the first bracket. One end of the second bracket is used to install a laser pointer.

[0008] The locking buckle includes a locking block and a latch. The two ends of the latch pass through the two ends inside the locking block and are fixed by threads. The first bracket and the connecting base rod pass between the locking block and the latch.

[0009] A further improvement is that the connecting base rod includes support anchor cables and anchor rods.

[0010] A further improvement is that both ends of the buckle are provided with external threads, and the two ends of the buckle pass through the two ends inside the locking block and are locked by the nut and the external threads.

[0011] A further improvement is that a sleeve is provided below the front side of the first bracket, one end of the second bracket passes through the sleeve, and a fastening bolt is threaded on the sleeve and used to fix the second bracket.

[0012] A further improvement is that the top of the laser pointer is provided with a mounting block, and the mounting block is sleeved on the outside of the second bracket.

[0013] A further improvement is that the top of the mounting block is provided with a knob bolt, which is used to fix the mounting block and the second bracket.

[0014] A further improvement is that the inner end face of the locking block is provided with an arc groove that is adapted to the first bracket, and the arc groove is covered with rubber.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model adopts a locking buckle and a fixed bracket. The fixed bracket is locked to the connecting base rod by the locking buckle.
